The first Pokemon isn't even shaded correctly. The design isn't Pokemon-ish. Look at an official Pokemon and this.
Another thing, the eyes of the first Pokemon are both the same size, almost exact. When you're looking at someone from an angle, that can't be possible.

The second Pokemon is also shaded horribly. Apart from that, I don't even know what it is.

The gym badge is far too symmetrical, and not shaded properly again...

EDIT: The attached pics show the *various* sources of light used in shading O.o
And the second Pokemon looks even more horrible without the blue background...
Don't let my language demoralize you, you can do better.
